1 0 all whom it may concern 3e it known that I, Janos AUGUSTUS SUL- iirlhm, of the city of Victoria, Province oi British Columbia, Dominion of Canada, have invented certain new and useful improvements in Automatic Ships-Telegraph Alarms; and I do hereby declare the following to bee full clear and exact description of: the same.

My invention relates to improvements in automatic ships telegraph alarms, and the object of the invention is to devise audihle means for indicating to the ships engineer when the position of the way-slmtt does not corrcspoinl to the position indicated by I 5 to a portion of the engine column or other the ships telegraph, and it consists essentially oi? the ships telegraphic apparatus provided with a pair oft contacts one on the astern side of the device, and one on the ahead side, a core of insulating material supported. in a suitable raising, a plunger supported within the core and forming a movable contact, connecting means between the plunger and the ivav-shatt and a stationary contact supported by the core and with which the plunger contact is pern'lanently in engagement. A. pair of contacts also carried by the core with which the plunger is alternately in engagement. ii circuit wire leading from the permanent contact through a bell and hatterv, to a ground contact on the telegraph device, and circuit wires connect ing the two renniinii'ig contacts villi the contact plates on the telegraphic device, all as hcreinatter more fully set torth and described in the accompanying specification and drawin in the drawings: The figure re n.'esents a partially diagrammatic and partially sec-- tional view of my device.

In the drawings like characters of reference indicate correspoiuling parts.

A is the telegraph device constructed in the usual manner with the ahead indications on. one side of the dial, and the aster-n indications on the other side oi the dial, and the usual indicating pointer .13. operated by a handle in the pilot house. The pointer it. of the device is adapted to serve as a contact iii'iger.

."i is an are shaped contact plate located on the ahead side of the telegraph device Hi. The plate A" is provided with a terminal A is a similar plate located on the astern side of the telegraph device A, and provided with contact post A it will be readily understood. that when the handle is swung in the direction indicated by the arrow that is toward the ahead portion, the pointer A will engage with the contact plate A3, and when the handle is swung in the opposite direction to that indicated by ill, arrow, or toward the aster-n portion the pointer carried thereon will ongage the contact plate A.

5 is a casing); secured by suitable means convenient place. The casing 5 insulated on its inner side and is provided with an opening A which. is threaded to receive a conduit tor carrying wires.

B core oi insulating material. secured within the lining A oil the casing; o by screws B and B is an orifice extending vertically through the center oi the core 13, and B, B and ll are openings extending from the 'ieriphecv ot the core into the vertical ori lice B B a vertical channel extending; from the top oi. the core into the opening l-l B" is a similar channel extending {in the top oil the core into the opening ll (l is a contact finger secured to the outside the core in the channel ll by screws C:

The lower end of the linger extends horizontally through the o 'iening ll and is provided with upturned end C. D is a similar contact to the contact C, the contact l) ex" tending throusrh the opening li into the center orifice J E is a contact also similar to the contact C and extei'idinp; through the orifice ll.

F is the way shaft.

(l is a vertical. plunger rod having vertical hearir formed by a stntling box ii on the casing Q is a linl: i'zonnccted at its upper end by lniuchlc joints (9: to the plunger rod G the being; connected by lower end of the link G knuckle joints G to the way shaft F, or corresponding element in case of a turbine or other engine. The link G is made with a turnbuckle having; right and left hand threads with a lock nut on one end, this I this o iti f the way haft, th 19911 H allows for adjusting position of movable contact 1.

H is an electric bell.

H is a battery.

2 is wire leading from the contact C to and through the bell H and the battery H i is also rung, indicating that the way rightly set, the circuit through the bell is to the ground circuit 3 connected to the telegraph dev ce. It might be advisable to connect this wire direct to spindle which carries pointer A? not be necessary in all cases. it pointer A in telegraph A, but this mightshaft is wrongly set. Of course, if the way shaft is kept. open, and therefore the hell does not ring.

From this description it will be seen that l have devised a very simple device, whereby the engineer will be immediately warned it a mistake is made in setting the way shaft, such audible signal immediately calling his attention to the telegraph indicator, thereby is already grounded through metallic con- 1 tact, it will only be necessary to run wire 2 to ground after passing bell H and battery H 4: is a wire leading from, the contact E to the terminal post A 6. is a wire leading from the contact D between. which extends the metallic contact j sleeve 1*.

l and I are metallic washers held against the washers l and l by the lock nuts I and i threaded on to the plunger rod G.

It will be understood that the contact sleeve 1* is always in contact with the contact finger U and is carried alternately into contact with the contact fingers D and according to the position in which the way sh aft is set.

All wires leading from box to telegraph A and to hell etc. should be carried through conduits. The bottom of box 5 is made do tachable to allow placing core inside.

In the position shown in the drawing, the way shaft is set in the ahead position. Should, however, the telegraph indicator be set to indicate the astern position, the circuit will be closed, through stationary contact finger C, through the wire 2 and bell H to the battery H and from the battery H to the ground contact 3, indicating pointer A, contact plate A, wire 6, con tact finger D and movable contact sleeve I". By this means the bell H is rung, thereby enal'iling him to immediately rectify his error.

ll 'hile l have shown the indicating finger 3 adapted for uses as a contact, it is obvious that if desired a separate contact I might be provided.

warning the engineer that the way shaft is 1 hen the Way shaft is set to the astern position, the movable contact let will be carried inwardly 1n the core B so as to elec- E extending on and around the inner face of trically connect the fingers C and E.

If when the way shaft is in this position the telegraph indicator indicates ahead, a circuit will be closed through contact fingers C, through wire 2, bell H, to the battery H and from the battery H through the ground contact 3, indicating pointer A contact plate A, wire a, contact finger E to and through the movable contact I. In

In turbines a way shaft would not be employed, but in such case the movable contact would be connected to the. corresponding part of the engine controlling means.
